My invention relates to paper making machines, particularly of theFourdrinier type. One of the objects of the invention is to provide asimple, practical and advantageous machine of the class specilied.

Another object of the invention is-to provide a' Fourdrinier machinewherein the table may be bodily moved or removed laterally to permitapplication of a new wire,

and may also be shaken to im rove the fibre and may also have its feeden ad'usted vertically to control the character o the fibre.

' Another object "of the invention is to arrange for the proper andcooperative opera` tion of the table, shaking mechanism and pulp holdingand feeding devices in carrying out the foregoing operations.

Other objects of the invention will appear and be pointed outhereinafter.

Referring tothe drawings, I show a Fourdrinier machine having a maintable portion 1 supporting rolls 2 for the wire 3. An ad- 'ditional orsupplemental end portion 1 is 70 also embodied in the machine shown, thesame supporting vacuum boxes 5-5 and 6-6and havlng a Jointed connection,as by pivot 7, with the main portion 1, and also having rolls 8-8 and9--9 for the wire. 75

The table comprising the sections or portions 1 and 1a is adapted forbodily removal in a sidewise manner, to permit the advantageousapplication of a new wire after a used one has been removed. To such'end 80 provision is made for moving the table out and back sidewise ontracks 11, 12 and 13, the table being shown in normal position in Fig.2, and moved out on said tracks in` Fig. 3. The table is provided withsuitable power mechanism for moving itout and back on said tracks, asfor example, an electric motor 15 (Figs. 1 and 5), power connected byspur wheel 16, gear 17, worm 18 and wheel 19 with driving shaft 20carrying wheel 21 for track 90 r 13, said shaft 20 being coupled toshaft 20a carrying wheels 22 and 23 for tracks 11 and 12, respectively.The rear or back side of the table is provided with wheels 25-25 (Figs.2, 4 and 6), for traveling on the tracks 95 11, 12 and 13, said wheels25 being preferably constructed, as shown in Fig. 6, with outsideportions 25m- 25a for purposes to be described later.

Tracks 11, 12 and 13 are preferabl con- 100 tinuous and of such lengthas t'oprovide for the table in both out and in positions and aresupported by posts or pedestals 26, 27, 28 andmaintaining tracks invertical position.

Posts or pedestals 28-have top surfaces which are inclined slightlyupward to elevate rollers and thereby permit tracks to be removed. Post29 has a wheel 29a for serving as a stop to limit backward movement ofta-y ble. Posts 27 and 28 are preferably connected together in pairs bycross beams 40.

Thus it will be seen that the entire table may be moved out to permitchanging wire f byoperating motor 15, and then moved back byl reversingthe motor, front edge of table normally resting with wheels 21, 22 and23 on tracks 13, 11 and 12, respectively, and rear of table restin withwheels 25 on track surfaces 37 of pe estals 28.

The mechanism for shaking the table disclosed herein is shown moreparticularly in Figs. 1 toll, inclusive. It includes a series (four areshown, Fig. 1) of upwardly extending reciprocatory or vibratory membersy 43-43 mounted on rock shaft 44, which is supported b bearings 45-45located on the floor, where y shaft 44 is low and vibration isprevented. Upright members 43 are connected with table section 1 bydetachable connections permitting table to be shaken as desired, andalso rmitting detachment or disconnection of s aking mechanism to allowremoval of table in direction away from such mechanism for applying newwire.

The connections between the two middle members 43 and table are shown inFigs. 2 and 1.5. They comprise straps 51 connected to yokes 52 which areon opposite sides of uprights 43, yoke members 52a sliding between rolls53-53 on boxes 54 which enclose uprights 43 and are also connected withstraps Boxes 54 arev provided with openable sides 55 normally held inposition so as to engage upright 43 by bolt 56 and hand nut Byunscrewing latter, side 55 may be swung about pivot bolt 58 so as toopen box 54 and allow separation of same from upright 43. The connectionfor the right hand end member 43 is shown inFigs. .17 and 18. Itcomprises a strap 51 such as previously described, but same has apivotal connection 59 with the jointed section 1* of the table, and'also a connection 60 with the shaking section l'of the table, wherebyboth sections are shaken. The connection for the left hind'- most member43 is shown in Figs. 3 and 4. It

,comprises a box 61, open at one side and having an inclined side and aconnection 63 for the brest roll bearing 64. Section 1 of table ismounted on flexible members 41 whose lower ends are secured to channelmembers 42, to permit shaking of rolls 2 and wire thereon withoutshaking the remainder of the table.

Vibratory members 43 are actuated by rocking of shaft 44 by verticallyvibrating arms 47 actuated by reciprocating members 47 a controlled byshaft 47 b which is turned by gear connection with power shaft 48., sothat rotation of latter will vibrate members 43 and so shake table.

Thus the whole table section 1 and brest roll also may be shaken asdesired and also detached from shaking mechanism to permit removal oftable for applying new wire, as shown in Figs. 2 and 3. A

Inasmuch as table is preferably shaken by shaking mechanism, tablesections 1 and 1 are preferably mounted at upper ends of flexiblemembers 41-41 whose lower ends are connected to and supported by sidechannel members 42-42, below which the various track wheels 21, 22, etc.are mounted, whereby table member 1 may be shaken relatively to members42-42. The shaking mechanism shown herein comprises a vibratory member43 mounted on ahrock shaft 44 operated by vibratory member 47 actuatedby driving members 48 and 49. Inasmuch as said shaking mechanism isshown, described and claimed in another application of mine, executed ofeven date herewith, Serial No. 648,962, filed July 2, 1923, Shakingmechanism for Fourdrinier machines, it will not be further described norclaimed herein.4

In accordance with present invention, the feed end of the table and thepulp holding and feeding devices may be adjusted vertically and in suchrelation as to cooperate properly 1n their various adjustments. Thisadjustment may be secured by means of suitable elevating devices andconnections for accomplishing the desired purposes. As an advantageousarrangement I have shown an electric motor 65 mounted on the top member66 forming with posts 67 a framework on which the pulp holding andfeeding devices are mounted. Motor 65 is geared to power shaft 68 so asto drive same and shaft 68 is connected by sprocket chain 69 with suplemental power shaft 70. The power shafts 68 and 70 raise and lower thefeed end of the table 1 and feed box 71 through suitable mechanismreferably controlling same, so that they s all rise and fall together inproper relationship, and also so that the feed on end posts 67 and slidedisclosed and. claimedbroadly in my Yokes 73 are connected with hangers76 which engagefthe ends of projecting members 77 on a cross beam 78which extends under,

neath and vengages feed box frame .pieces 7 9--7 9, so that raising andlowering of yokes 73 will elevate and lowerfeed box 71.

Yokes-74 are connected-with hangers 80 whose lower ends engageprojections 81 on the feed end of table section 1, whereby raising andlowering of okes 74'will raise and lower feed end of ta le, whereby itwill be seen feed box 71 and feed end of table will rise and falltogether. j j As a matter of further and specific improvement, provisionis made for tilting feed ,box 71 so that it will incline down toward thetable as itand the table rise. For this purpose I show guideways 83-83and 84-.84 ins or rollers 85 and 86, the former on side rames 87 on feedbox 71, and the latter on frames 88 on hangers 88a extending down belowfeed box 71, being preferably formed integral with frames 79. Guideways83 are preferably inclined in wardly and upwardly, and guideways 84outwardl and u wardly, as shown in Fig. 7, whereby feed ox 71 will ineffect be t1lted substantially about the feed end of table as bot-h riseand fall, thus insuring proper feed of pulp and proper cooperation ofdevices in the upward and downward adjustment. Guideways 83 may beadjusted by screw bolts 83'l and guideways 84 b screw bolts 84.

The brest roll on table is preferably made adjustable lengthwise of thetable to facilitate applyin a new wire and for other purposes. In t Aearrangement shown, said roll is mounted on slides arranged to slide inguideways 92 and provided with a rack 93 meshing with a pinion 94vonshaft 95 also carrying gear 96 meshing with pinion 97 turned by handle98, whereby rotation of handle 98 will adjust brest wheel 90 lengthwiseof the table.
